GRAIN-WEIGHER.

SPECIFICATION forming part of Letterslatent No. 693,199, dated February1 1, 1902.

Application filed November 12, 1900. Serial No. 36,315. (No model.) I

To all whom it may concern:

Be it known that I, DANIELW ILDE, a citizen of the United States ofAmerica, residing at Washington, in the county of Washington and Stateof Iowa, have invented certain new and useful lm provements inGrain-Weighers, of which the following is a specification.

My invention relates to an improvement in grain-weighers.

The present invention is an improvement on the grain-weigher disclosedin Letters PatiflslggNO. 411,514, granted to me September 24, I laboredwith this patented construction was that while the two pockets of the[hopper weighed alike in the factory, yet when it was placed on athresher if for any reason they did not weigh alike in all cases itcaused considerable trouble and loss and the difficulty was encounteredof devising any way by which they could be corrected. Sometimes theelevators would not stand exactly plumb, which would cause heavy andlight sides, and there seemed to be no way of obviating this difficulty.The object of my present invention is to entirely overcome thisobjection, and with this end in view it consists in certain novelfeatures of construction and combinations of parts, which will behereinaftermore fully described, and particularly pointed outin theclaims.

In the accompanying drawings, Figurel is a view in side elevation. Fig.2 is a vertical section, and Figs; 3, 4, 5, 6, and 7 are enlargeddetails. A

A represents abracket, which may be made of sheet-steel or other metaland preferably of the general form shown in Fig. 1, with a hole 1 at itslower end and an elongated slot 2 at its upper left-hand corner, whichslot is curved in the arc of a circle struck from hole 1 as a center, aswell as other accessories which will be described. A pair of plates B Bare secured tothe upright O at a suitably separated distance from eachother. These plates are provided each with a hole 3 at the outer edgeand through them the rod 4 passes, this rod also extending through hole1 of bracket A and affording a supporttherefor and acenter from whichsaid bracket may be swung when it is desired to adjust it with relationto the elevator D of the threshing-machine. This bracket One of thedisadvantages under which tom of the hopper.

is also held to the upright by means of a setscrew or, other means 5,passing through the curved elongated slot 2 in the'bracket. The

object of this slot is this: In the factory the weigher is put upwiththe uprightor backboard on an elevator which is perfectly plumb.

Inthe field where the thresher is at work if the elevator is not set soas to be perfectly plumb this bracket A is swung to the right or left,as the case may be, until itis adjusted, so that the weigher center ison a plumb-line, when the set-screw 5 is tightened and the bracket heldsecurely in position and the other parts of the weigher in accurateadjustment for work.

E represents the hopper.

ferred to, it having a central partition 6 and with the two openings 7 7at the bottom on 'eitherside of said partition; but instead ofbeingsupported at or near the center this 110pper oscillates on a rod 8,located at its bottom, upon which the hopper rests astride. This rodbears in the outer end of bail F, which latter is supported and turns onthe rod 1 in the plates B B. Gate G is likewise pivoted and hinged onthis rod 8, so that it swings on the rod as a center to alternately openor close one or the other of the openings 7 7 at the bot- At .one endthe gate is provided witha fork 9, and an oscillating arm 10, pivoted onthe corresponding end of the hopper, is provided with anantifriction-roller '11, which operates in said fork and as the armoscillates causes the gate to swing back and forth with each of itsmovements,but in the opposite direction therefrom. A steady-rod 12 ispivoted at one end to the bracket Aand at the other to the upper end ofthe oscillating arm, so that as the hopper vibrates back and forth withthe depression caused by the full complement of grain in one side or theother the oscillating arm is caused to swing in an opposite directionand with it the gate or door G is forced aside to open the chambercontaining the grain and allow the latterto discharge, after which theupward movement takes place as the weight is removed from the hopper andthe other chamber is beingfilled with more grain.

On one or both ends'of the rod 8a crook 14: is formed and from this orthese spiral spring This is in the main like the one disclosed in thepatent reor springs extend to an adjustable block 15, which block ismade adjustable by the screw 17, operating therein, and which adjustmentcauses the desired tension upon the spring, as the nearer the block isto the top of the bracket the stronger the spring and the more grain isrequired to lower the hopper, and the farther the block from the top ofthe bracket the less the tension, and in consequence the smaller theamount of grain required to lower the hopper. A scale 16 is placed atone side of the block toindicate where to adjust the latter for certainpredetermined weights. It is obvious that the spring or springs may beso placed as to pull directly upward, although I prefer the positionindicated in Fig. 1.

At the upper right-hand end of bracket A a large slot 18 is formed, andthrough this a lug 19, secured'to the hopper, projects. A plate 20,pivoted centrally above this slot, is provided with two curved elongatedslots 21 21, upon arcs of which the pivot 22 is the center, andset'screws 23 23 are employed for setting this plate in its adjustedposition. It will be seen that the ends of this plate serve as shouldersfor the lug 19 to strike and that the hopper has to descend until thelug reaches the bottom of this plate, when it is free to move along thebottom or lower edge thereof to the other end, which operation placesthe other pocket or chamber of the hopper in position to receivethegrain. It

per has to descend before the lug clears the plate the more it draws outthe spring or springs,and theincreased power of the spring has to bebalanced by an increased quantity of grain. Now if it is found that onepocket or chamber of the hopper is weighing heavier than the other oneit is simply necessary to raise the end of the plate which operates theheavy pocket and lower the end which operates the light pocket, thuskeeping the combined weight of the two pockets the same as well asmaking the two pockets dump with equal weight. made perfect, whether theelevator happens to be perfectly plumb or not, and the weighing of thegrainis rendered absolutely accurate at all times.

It is evident that slight changes might be madein the form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I do not wish to limitmyself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is as follows:
